warning: ‘struct ’ declared inside parameter list

warning: ‘struct ’ declared inside parameter list

[Fundu]

i'm running ubuntu 8.04 with gcc-4.2 
and i'm getting 

mb_con.h:43: warning: ‘struct query_resp’ declared inside parameter list
mb_con.h:43: warning: its scope is only this definition or declaration, which is probably not what you want

here's a snippet of how .h file looks

struct query_resp_type
{
  int type;
} query_resp;

void send_req(struct query_resp* resp);


what i don't understand is why this warning when i have declared the struct before the function in the header.

what am i missing ? 

thanks in advance !

you defined here _both a type and a variable_.
this should not be done inside a .h file...

maybe you expected to redefine a type, and forgot to 'typedef' ?
==
struct query_resp_type {
  int type;
};

typedef struct query_resp_type query_resp;
==
after such a typedef, you will be able to use type 'query_resp'
(note that 'struct' is not part of the type name)

wrong. type 'struct query_resp' does not exist.
but 'struct query_resp_type' does.
